Saba Freiburg studio search buttons does not function

Dear members,

Yesterday I buyed this great Saba Freiburg studio tube receiver. All seems to work fine, including the auto tuning correction function that correct for mistuning with the motor but the two search buttons who are lokated at the bottom of the radio and who are intend to search for the next strong station  does not function. I allready clean the contact but without any improvement. Is there anyone who know what may be the root cause of this?

Another related question, the motor becomes very hot in the automatic on position. Is this normal? Is ther something I can do to avoid this?

Any suggestion where to look will be appriciated.

Many thanks in advance,

Abbe

You will find special advice in this article
At other models like Freiburg 7 and Freiburg 100 or 125 you will find more information about the tuning function and its repair.


Please post your questions in the future directly from the model page, I moved your post to the model page.

Greetings!
 If, after following Herr Grund's and other's excellent advice there remains the problem, I ask the following:

 Have the pivot points of the mechanical linkages controlled by the auto tuning push buttons been checked and verified for absolute freedom of movement and full range of motion? (This mechanical binding seems to be a common problem with these newer (nach 1960) and similar models.)
 
 Will the motor activate if pressed for the 'schnellauf' (fast forward/ reverse) function?
 
 Also, have the small contacts at the rear of the remote control jack been checked to make sure they have continuity?
(This may present a "no search function" if a remote control unit had been installed for a length of time and has subsequently been unplugged from the receiver. Though the contacts consist of of silver, dust may accumulate between them, causing an "open" control circuit for the auto tuning (suchelauf) latch solenoid. )
 
 These two hints are for  common failures of the automatic tuning on the later models, including the "Studio."

 Good Luck with Repairing this fine receiver!
